Hi I need to calculate the Energy Rating Index, I need Openstudio-Eri the hpxml for which I need the Openstudio-hpxml. how should I install these measures in the openstudio application, I copied it in the measures folder and tried to use it and it gives me error. someone help me please.
You can't perform an ERI calculation, which requires running multiple energy simulations (e.g., Reference Home, Rated Home, etc.), using the OpenStudio Application. Rather, you run the calculation using the OpenStudio CLI.
Please read the Usage Instructions on how to run an ERI calculation. There's also a lot of description on capabilities, inputs, outputs, etc. in the documentation.
OpenStudio-ERI requires a building description in an HPXML file format. is there any way for openstudio application to generate the building hpxml file or the only way is to do it manually?
Thanks for your help.
ERI calculations require very specific high-level inputs, which is what HPXML is intended for. OpenStudio models, on the other hand, have very detailed inputs (from which you cannot back out the high level inputs) and are often missing the necessary information to drive an ERI calculation.
Also, OpenStudio-ERI and the HPXML files are intended for software developers, not end users. There are several software tools that create HPXML files and run OpenStudio-ERI, including Rem/Rate, HouseRater, and APEX. There is nothing that stops you from manually creating HPXML files, but it is not a trivial undertaking.
Thank you very much, now the idea is clearer to me.
